FDA Approval Insights: Orca-T Raises the Bar for Allogeneic Transplants in Hematologic Malignancies: With Everett Meyer, MD, PhD

In today’s episode, we welcomed Everett Meyer, MD, PhD, an associate professor of medicine (blood & marrow transplantation), an associate professor of pediatrics (stem cell transplantation), and an associate professor of surgery (abdominal transplantation) at Stanford Medicine in California.

In the exclusive interview, Dr Meyer discussed the significance of the June 2026 FDA approval of allogeneic regulatory T cell–based immunotherapy with hematopoietic stem and progenitor cell (HSPC) and T cells-vldq (Tregzi; Orca-T) for use in matched donor hematopoietic stem cell transplantation (HSCT) with a myeloablative preparative regimen, for hematopoietic and immunologic reconstitution, and to improve chronic graft-vs-host disease (cGHVD)–free survival in the treatment of adults with hematological malignancies. 

Dr Meyer also broke down what the approval of Orca-T means for the transplant field, detailed the design and key outcomes from the phase 3 Precision-T trial (NCT05316701) that supported the approval, and outlined how this approach could be integrated into clinical practice.
